Nearly 30 years since the birth of laser myopia surgery, it has benefited more than 30 million myopic patients worldwide, leaving behind their glasses to their own distress. In February 2013, U.S. President Barack Obama announced the awarding of the National Technical Award to Dr. Gholam Peyman, the founder of LASIK myopia surgery in the United States. In February 2013, President Barack Obama announced that he was honoring Dr. Gholam Peyman with the National Award for Technology and Innovation for his efforts and scientific excellence in the field of myopia. Laser myopia surgery, which has been in development for decades, has once again been recognized by society and the medical community. The procedure has become normalized in its native Europe and the United States. When you are determined to undergo laser myopia surgery after suffering from glasses after glasses, your heart is inevitably full of doubts and apprehensions: Is it possible to operate? Is the surgery safe? How should I go about this process? Surgery overview: Myopia laser surgery requires an examination before surgery, and the whole process does not require hospitalization. Of course, if possible, it is more comfortable to rest 1-2 days after surgery. The cost of myopia laser surgery is not yet covered by medical insurance in China, so it is fully self-paying (it is also known to be a self-paying procedure in Europe, America and Japan). The whole process is divided into the following five steps: initial understanding → selection of hospital → pre-operative examination → arrangement of surgery → post-operative review [initial understanding] Not everyone can do myopia laser surgery, which is determined by the eye and other factors of the body. The criteria for whether or not you can have surgery are clearly defined in the People’s Republic of China Health Industry Standard “Quality Control of Excimer Laser Corneal Refractive Surgery” (implemented on February 1, 2012), and doctors will check each preoperative examinee according to these criteria to ensure the safety of the surgery. You can first understand the criteria to see if you meet: 1. Indications for surgery Patients with myopia, hyperopia, astigmatism or presbyopia, who have a desire to improve their refractive status through keratoconus surgery, are psychologically healthy, have reasonable expectations for the efficacy of the surgery, and are excluded from contraindications to surgery by preoperative examination. 2. Absolute contraindications to surgery (patients with any of the following conditions should not undergo surgery): active inflammation of the eye, periocular septic lesions, severe ocular appendage lesions such as eyelid defects, malformations, chronic dacryocystitis, etc., diagnosed conical cornea; severe dry eye disease, for LASIK, central corneal thickness <450um< span="">, or expected remaining stromal bed under the corneal flap thickness < 250um, uncontrolled glaucoma uncontrolled systemic connective tissue disease and severe autoimmune disease, uncontrolled diabetes mellitus, systemic infectious disease. 3. Relative contraindications (the presence of one of the following conditions may adversely affect the operation, postoperative recovery or surgical efficacy, but in special cases, after full communication and explanation with the patient and taking appropriate measures, surgery can be performed at the discretion of the patient) Age less than 18 years old, refractive error of more than 100 degrees in the last two years, myopia more than 1400 degrees, hyperopia more than 600 degrees, astigmatism more than 600 degrees Blindness or low vision in the contralateral eye, dry eye, mild risk of fissure closure, mean central refractive power of the cornea less than 38m-1 or more than 48m-l before the initial surgery, history of herpes simplex or herpes zoster keratitis, corneal stromal or endothelial dystrophy, significant corneal irregularity astigmatism; cataract affecting corrected vision, retinal detachment, macular hemorrhage, etc. within 2 years after penetrating corneal transplantation History of fundus disease, glaucoma, diabetes, pregnancy, lactation, epilepsy, anxiety disorders, depression and other mental disorders. Selecting a hospital] A thorough eye examination is required before surgery, that is, to determine the parameters of surgery and to check eye diseases. Therefore, it is best to select a hospital for surgery and then go directly to that hospital for preoperative examination, so that you do not have to repeat the examination and waste time and money (preoperative examination fee will not be refunded if only examination is performed without surgery or if the examination result is not operable). Due to the differences in the examination instruments and techniques of each hospital, the hospital will not use the examination data of other hospitals to operate directly. Nanhai Hospital of Southern Medical University has the world's most advanced German Eagle Vision OCULYZER 3D anterior segment analysis diagnostic system for preoperative examination of myopia. One of the most important features is that it provides a more advanced screening function for cone corneas, and the OCULYZER anterior segment analyzer can measure the anterior and posterior corneal surface topography compared to the simple corneal topography commonly used in other hospitals. data, corneal morphology, anterior chamber volume, atrial angle morphology and other data, providing a higher level of safety assurance to ophthalmologists and myopic surgery friends. The main things that individuals should consider when choosing that hospital for surgery are the experience of the hospital surgeon, the surgical approach, the instruments and the price (the surgeon at Nanhai Hospital has over 10 years of surgical experience). Guangzhou hospitals around the pre-operative examination fee 300 - 600 yuan ranging (Nanhai Hospital is 300 yuan), the mainstream of domestic surgery there are two ways: 1, the traditional excimer laser surgery, the instrument is the use of corneal lamellar knife + excimer laser instrument, surgery costs a pair of eyes about 4,000-6,000 yuan. (Price Bureau pricing is 5000 yuan) 2, femtosecond laser surgery, the use of femtosecond laser instrument + excimer laser instrument, the cost of surgery 12,000-16,000 yuan ranging. (Price Bureau pricing is 12,000 yuan) Guangzhou, Foshan area is currently only Nanhai People's Hospital femtosecond laser surgery is less than 10,000 yuan, and is the most advanced da Vinci femtosecond laser instrument. The Foshan price bureau pricing is 12,000 yuan, because it is a public hospital, to benefit the majority of myopic friends and set a preferential price only. Although it is an individualized surgery, the total cost only includes the cost of examination, surgery and eye drops, no more separate charges. So many people from Guangzhou Shenzhen and other places come to Nanhai Hospital for myopia laser surgery, in addition to the charm of the da Vinci femtosecond laser, the cost of surgery is also a big attraction. And Nanhai People's Hospital has convenient transportation (Guangfo subway directly to Nanhai Guicheng). Thursday examination Friday morning surgery, Friday afternoon can return, only need to stay overnight in a hotel near the hospital, the total expenses can still save several thousand dollars. Compared to traditional excimer laser surgery, femtosecond laser applied to refractive surgery is another technological revolution in ophthalmology. Over 90% in the United States and 100% in Japan are opting for this type of surgery. Femtosecond laser surgery is all-laser surgery, the whole process of "no knife", is the use of femtosecond laser production of corneal flap, and then use the excimer laser cutting cornea, the advantage is that the corneal flap thickness error is very small, less than 15 microns (conventional lamellar knife cutting error up to 30-40 microns), femtosecond laser safety, adaptability greatly improved, better post-operative visual quality. The postoperative visual quality is better. Pre-operative examination] Pre-operative examination should pay attention to the following points: 1, to stop wearing contact lenses to wear frame glasses: because contact lenses directly contact the cornea, affecting the accuracy of the examination results. Soft contact lens even wearers should stop wearing 48 to 72 hours, long-term wearers need to stop wearing 1 to 2 weeks; with hard corneal contact lens wearers stop wearing 4 to 6 weeks; OK lens stop wearing 3 to 6 months. 2, before going to the hospital examination can be through the network, telephone, QQ and other ways to contact the staff to get better guidance, so that you can straightforward and save time and effort. 3, the examination to dilate the pupil, dilate the pupil within a few hours after the blurred vision, it is recommended not to drive back, so you have to arrange your own return transportation. 4.The whole set of pre-operative examination will take 1 and a half hours, and if the examination results can be operated, eye drops will be prescribed, consent forms for surgery will be signed, surgical education will be given, and other preparations will take about 2 and a half hours, so you should arrange your trip according to the hospital's working hours. If you're not sure if you're ready for surgery, you can make an appointment with your doctor. Most hospitals are very humane and will schedule surgery on Fridays, so that working people and students can get enough rest on the weekend after surgery. After the surgery, you can leave the hospital. It is best to have someone with you on the day of surgery to share the psychological pressure and to do general daily care (no one can accompany you, I have seen people who took two trips home on the bus after surgery). The surgery at Nanhai Hospital takes only 8-10 minutes, and the surgery is completed in one go, without waiting for the surgery bed to be changed. (Some hospitals have femtosecond laser, because the eye will produce bubbles during the operation, after the femtosecond laser to close the eyes and wait for 20 minutes to play excimer laser, the operation process is long, the pain increases, the psychological fear increases). In the 3-4 hours after surgery, you will generally feel a sense of foreign body, photophobia, tears, slight pain and other discomfort in the eyes. The Femtosecond Excimer Laser Myopia Treatment Center at Nanhai Hospital in Foshan is generally focused on surgery every Friday morning. The surgery is performed in the morning, and the eye patch is removed and rechecked at about 4:00 p.m. After the surgery, you can see more clearly. You can go to work and drive the day after surgery. In the early post-operative period, you will feel discomfort such as dry eyes and easy fatigue, but it will not affect your general work and life much. The key period is one month after the surgery. Please remember a few general rules: prevent infection, prevent trauma, follow up on discomfort, and follow up on specific details such as following the doctor's prescription for eye drops, avoiding confrontational sports, and avoiding eye abrasions, collisions, and sand and dust in the eyes. Vision and visual quality can be affected by lifestyle habits, sleep, emotions and diet, so in the early postoperative period, we need to pay more attention to ensure the quality of sleep and avoid spicy, hot and irritating diet. Postoperative review] The time for review is similar in all hospitals. The time is the day after surgery (or 6 hours after surgery on the same day), one week, one month, three months, six months, one year, and if there is any discomfort, consult the doctor at any time. Early review after surgery is relatively important, try to take time to review. At present, the six post-operative routine re-examinations at Nanhai People's Hospital in Foshan are free of charge, and most hospitals charge re-examination fees according to your examination items. In the early post-operative period, you will have a process of adaptation to your vision, eye sensation, and certain habitual movements of wearing glasses for a long time. Of course, this is some good changes, and you will no longer be bound by your glasses when you go surfing on the beach, playing ball, climbing mountains, performing on stage, etc. You will live a new life in a relaxed and clear world from now on!
